The default connect string for the samples should work without 
modification if you have Sql Server Express installed on your development 
machine. There are, however,
a few cases in which trouble might occur.</p>     

<ul>
<li>On some SQL Express installations, you may not have the rights to start a
user instance. If you get an error message to that effect, try removing the
clause ";user instance = true" from the connection string.</li>

<li>Be sure that the copies of the northwind database that you are accessing are not
marked read only. If necessary, browse to the copy of NORTHWIND.MDF you are trying
to access, right click on the file, chose properties. Clear the <strong>Read-only</strong>
attribute.</li>

<li>
On some slow machines, or when using a virtual pc, users have reported that some
database applications give errors the first time they run. Try running the sample
two or three times.</li>

<li>If you are using SQL Server instead of SQL Server Express, you will need to
change the connect string. Here is an alternate connect string that you can modify 
for your own purposes if you are not using Sql Express but have Sql Server 
available.</li>
</ul>

<pre>string connString = 
  "server=[SERVER_NAME];database=northwind;user id=[USER_NAME];password=[PASSWORD]";
</pre>

<p> You will probably need to modify the words SERVER_NAME, USER_NAME, PASSWORD wherever it 
appears in the sample connect string.&nbsp; For example, your connect string
    might look like this:</p>
    <pre>
string connString =        
  "server=MyServer;database=northwind;user id=sa;password=MyPassword";<br />
    </pre>
